Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake cleaner, jack stands, lug wrench, brake fluid.
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Use the lug wrench to loosen the lug nuts.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Remove Caliper

Locate the caliper mounting bolts using a socket set.
Remove the bolts and carefully slide the caliper off the brake rotor.
Support the caliper using a bungee cord or similar tool to avoid strain on the brake line.

4. Inspect and Replace Components

Inspect Brake Pads: Check for uneven wear. Replace if necessary.
Inspect Caliper Piston: Ensure it moves freely. If seized, consider rebuilding or replacing the caliper.
Replace Brake Caliper: If the caliper is damaged or leaking, replace it with a new or remanufactured unit.

5. Reassemble

Reinstall Caliper: Slide the caliper over the new brake pads and rotor. Secure it with the mounting bolts.
Torque the Bolts: Tighten the caliper mounting bolts to the manufacturer's specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and tighten the lug nuts in a crisscross pattern.

6. Final Checks

Refill Brake Fluid: If any fluid was lost during the process, refill the brake fluid reservoir with the appropriate type (DOT 3 or DOT 4).
Reconnect Battery: Reconnect the battery terminal.
